HOSE NOZZLE.

Application led April 29, 1920. Serial N'o. 377,475.

To all wlmi/i, t may cmwern Be it known that I, SIDNEY C. SLAnnErI, acitizen of the United States, and a resident of the city of New York,borough of Manhattan, in the county and State of New York, have inventedcertain new and useful Improvements in Hose Nozzles, of which thefollowingr is a full, clear, and exact description.

Among the principal objects which the present invention has in view are:to rotate a nozzle of the character mentioned by the force of theoperating stream therefor; and to avoid frictional resistance to thenozzle in its Inovement through the medium belng operated upon.

Drawings.

Figure 1 is a side view partly in section, of a nozzle constructed andarranged In accoi-dance with the present invention;

Figure 2 is a cross section of .the nozzle, the section being,r taken ason the line 2-2 1n Figure 1;

Figure El is a cross section of the nozzle,V

the section being taken as on the line 3-3 in Figure 1.

The present invention has for its object more particularly animprovement of the structure disclosed in the patent granted to John T.Burns March 21, 1916, and numbered 1,176.518. Nozzles constructed inconformity with the said patent have` one objection. in that they meetwith resistance when driving through immobile substances, whichresistance retards their forward move ment, caused by delivery of waterunder pressure from the rearwardly opening orifices provided in thenozzle.

Nozzles of the character mentioned constructed in accordance with thepresent invention avoid this pressure by rotating on their axis therebyshifting the point of contact with the resisting medium.

As seen in the drawings, a nozzle 1() is provided with a bulged body. toform an interior chamber 11. From the chamber 11 water is emitted by wayof a contracted spout 12, and a series of propelling orifices 13. Theorifices 13 in the present invention are extended through the wall ofthe bulged body of the nozzle 10. to project the water from the chamber11 backward, and as nearly parallel with the throat 14 of the nozzle asis practical. The streams emitted from the orifices being larger inarea, overcome the resistance of the-stream passing from the spout 12,and thus force the nozzle l() and parts connected therewith forward, inthe direction of the stream emitted from the nozzle 12. To impart arotary action to the nozzle 10, the orifices lil in the preferred formof the invention shown in Figures 1, 2 and 3 are inclined somewhat fromplanes coincident with the axis of the neck 14. The same inclinationbeingr imparted to each of the orifices, the same rotary thrust is givento the nozzle which, while being forwardly propelled in the direction ofthe arrow a, is also rotatably propelled in the direction of the arrowb.

The nozzle 1() is operatively connected with a reducer connection 15,which is provided with a threaded section 16, for couplingr with a hoseof any desired character and description. The nozzle is operativelyconnected with the reducer 15 by a coupler 17, the neck of which isthreaded to engage the threads provided on the neck 18 of the nozzle.The lower end of the coupler 17 is ared to form a hell-like extremity19. The extremity 19 is fiared to fit the reducer 15 at the centralopening thereof, and to avoid the friction of the metallic connection aseries of halls 2() is interposed between the walls of the reducer 15and of the extremity 19.

Where it is desired a packing 21 is disposed in a groove formed adjacentthe edge of the extremity 19. said packing resting normally against thesurface of the reducer 15. The molded extremity 22 of the neck 18 isdisposed adjacent to the edge of the opening in the reducer 15,toprevent the dislodgment of the extremity 19 from the wall of the reducer15 to permit the escape of the balls 20 from service disposition.

From the foregoing it will he seen that when water is turned on to thehose with which the nozzle is connected, it is admitted to the chamber11 of the nozzle 10. and from thence emitted. under pressure, from thespout 12. and the orifices 13. The pressure of the water passing fromthe orifices 13 is sufficient to propel the nozzle 10 and partsassociated therewith forwardly. while revolving the said nozzle on thebearingr in the reducer 15 formed by the balls 20. Thus. if the nozzle10 in boring through an obstacle, should become attached to theobstacle, the

twisting action provided for the nozzle would enable 1t to escape fromthe frlctlonal engagement.

Claims.

1. A nozzle as characterized comprising an enlarged head having aplurality of openings for discharge theiefroni, said openings beinglocated at the rear of said head for delivering liquid which passesthrough said head to the rear thereof, and said openings being arrangedwhereby the passage of the liquid therethrough will impart an annularthrust to the nozzle and rotate the same.

2. A nozzle as characterized comprising an enlarged head having aplurality of openings for discharge therefrom, said openings beinglocated at the rear of said head for deliverin liquid which passesthrough said head to tie rear thereof, and means for rotating the saidnozzle, said means supplementxng said openings, said openings beincorrespondingly inclined to the axis of sai nozzle to impart an annularthrust to said nozzle.

3. A nozzle as characterized comprising an enlarged head having aplurality of openings for discharge therefrom, said openings beinglocated at the rear of said head for deliverin 'liquid which passesthrough said head to t ie rear thereof, and means for rotating the saidnozzle, said means suppleinenting said openings, said openings beingcorrespondingly inclined to the axis of said nozzle to impart an annularthrust to said nozzle, and means for connecting said nozzle in serviceto a hose, said means embodying a connection pivotally united to saidnozzle.

4. A nozzle as characterized comprising an enlarged head having aplurality of openings for discharge therefrom, said openings beinglocated at the rear of said head for delivering liquid which passesthrough said head to the naar thereof, means for rotating the saidnozzle, said means supplementing said openings, said openings beingcorrespondingly inclined to the axis of said nozzle to impart an annularthrust to said nozzle, means for connecting said nozzle in service toa'hose, said means embodying a connection pivotally united to saidnozzle, and friction reducing devices interposed between said connectionand said nozzle for reducing the resistance to the turning effort of thecontents of said nozzle.
